When I use Fourier, Save or Plot on a big list (100,000 numbers),
memory usage increases, and doesn't decrease when the command is
completed: <<list;
f=Fourier[list];
Plot[Abs[f]]; (*might already run out of memory here, depending on the
number of points that are plotted*)
Save[f]; (* It cannot complete this command even if Plot is ommitted ;
Kernel has 40 MB of memory*)
Any ideas?
